Eating a handful of almonds a day significantly increases the production of butyrate, a short-chain fatty acid that promotes gut health, according to a recent study.
Researchers used artificial nests to test two methods for reducing the nest predation of vulnerable and endangered ground-nesting birds. The study showed that red foxes can be more easily deceived into not eating bird eggs than raccoon dogs. The methods could be used alongside hunting and offer an alternative, non-lethal solution for creating protection for vulnerable prey.
For proper operation, drones usually use accelerometers to determine the direction of gravity. Scientists have now shown that drones can estimate the direction of gravity by combining visual detection of movement with a model of how they move. These results may explain how flying insects determine the direction of gravity and are a major step toward the creation of tiny autonomous drones.
The research framework developed, along with observational data from the Webb Space Telescope, will enable scientists to efficiently assess the atmospheres of many other planets without having to send a space crew to visit them physically. This will help us make informed decisions in the future about which planets are good candidates for human settlement and perhaps even to find life on those...
The skin is a large, complex organ, and it serves as the body's primary interface with the environment, playing key roles in sensory, thermoregulatory, barrier, and immunological functioning. As floods, wildfires, and extreme heat events increase in frequency and severity, they pose a significant threat to global dermatological health, as many skin diseases are climate sensitive.
In response to a high-competition environment, Trinidadian killifish evolve larger brains, increasing their fitness and survival rates, according to a new study.
Ahead of the global meeting of the Conference of the Parties in Montréal, Canada, which decides new targets for nature, a new study outlines an urgent need for larger numbers and better-supported protected area staff to ensure the health of life on Earth. Scientists argue that there are not enough rangers and other staff to manage even the current protected areas around the world. The authors...
The iconic, glacier-carved features of Yosemite Valley appeared sometime during the past 50 million years, when Sierra Nevada granite was first exposed, but geologists have not been able to establish exactly when the valley as we know it today appeared. Using a relatively new rock analysis technique park geologists have narrowed it down to within the past 10 million years, and probably within the...
Using the James Webb Space Telescope to look back in time at the early universe, astronomers discovered a surprise: a cluster of galaxies merging together around a rare red quasar within a massive black hole. The findings offer an unprecedented opportunity to observe how billions of years ago galaxies coalesced into the modern universe.
A new study has revealed that chimpanzees share a human tendency to unintentionally synchronize their steps when walking alongside one another.
High-entropy alloys (HEAs) are promising materials for catalysis and energy storage, and at the same time they are extremely hard, heat resistant and demonstrate great variability in their magnetic behavior. Now, a team has gained new insights into the local environment of a so-called high-entropy Cantor alloy made of chromium, manganese, iron, cobalt and nickel, and has thus also been able to...
Joint research has found adult incontinence products are a far bigger waste problem than baby diapers, and with an aging population, the situation will get worse in the next decade.
Stock purchases by U.S. senators generated abnormal positive returns for the firms whose stock was purchased, according to a new study by U of A researchers.
After journeying this summer through a narrow, sand-lined pass, NASA's Curiosity Mars rover recently arrived in the "sulfate-bearing unit," a long-sought region of Mount Sharp enriched with salty minerals.
Using the James Webb Space Telescope to look back in time at the early universe, astronomers discovered a surprise: a cluster of galaxies merging together around a rare red quasar within a massive black hole. The findings by Johns Hopkins University and an international team offer an unprecedented opportunity to observe how billions of years ago galaxies coalesced into the modern universe.
University of Massachusetts Amherst research into genetic mutations that affect circadian rhythms offers new insight into the rest-wake cycle and provides a new model for investigating human disease and ultimately developing medical treatments.
Dryland ecosystems cover about 40% of land on earth and support more than 2 billion people, and, once degraded—through overgrazing or inadequate irrigation—they are difficult to restore. One technique for restoring ecosystems with native plants "direct seeding" is promising, but has many drawbacks.
Some of Victoria's most important agricultural regions are among the areas worst hit by severe floods inundating the state this week.
Engineers have developed a stable water-splitting catalyst for clean hydrogen generation that could replace expensive iridium catalysts.
Scientists have puzzled over the origin of Namibia's fairy circles for nearly half a century. It boiled down to two main theories: either termites were responsible, or plants were somehow self-organizing. Now, researchers benefiting from two exceptionally good rainfall seasons in the Namib Desert, show that the grasses within the fairy circles died immediately after rainfall, but termite activity...
A new study identifies common and rare gene mutations that impact radiation resistance and sensitivity, an important step toward providing more individualized and effective radiotherapy for patients with cancer. The discovery ultimately could allow radiation dosage to be calibrated based on genetic mutations. Radiotherapy continues to be delivered using generic schedules and doses, unlike newer...
College-educated Black women in the United States give birth to fewer children than their white and Hispanic counterparts, according to a new study. The study examines the interplay of race, ethnicity, and education in shaping the fertility levels of U.S. women born between 1960 and 1980.
Chewed plants are helping veterinarians provide personalized health care to wild, endangered mountain gorillas in East Africa.
